Abstract: A method of retrofitting a service rig includes obtaining a service rig having a powered service equipment for performing well service operations, an engine, and a transmission connected to and powering the powered service equipment. The method also includes disconnecting the engine and the transmission from the powered service equipment and removing the powered service equipment. The method further includes retrofitting the service rig with a plurality of electrically powered equipment for performing the well service operations, wherein the plurality of electrically powered equipment are operable while disconnected from the transmission.

Abstract: A sound reduction system for a rig having a sound producing equipment includes an enclosure at least partially enclosing the sound producing equipment and a sound absorbing material provided on a surface of the enclosure. The rig can be a mobile rig having a chassis, and the sound producing equipment is disposed on the chassis.

Abstract: A method of converting a carrier rig to a trailer rig is provided. The carrier rig has a carrier rig chassis, a suspension system, a transport system, and rig service equipment. The method includes removing one or more of the suspension system, the transport system, or the rig service equipment. The method also includes attaching a chassis extension to the carrier rig chassis to form a trailer rig chassis of the trailer rig. The chassis extension is configured to couple to a transport vehicle.

The method also includes retrofitting the service rig with a plurality of electrically powered equipment for performing well service operations.

Abstract: A method of operating a rig includes maintaining a drum of the rig in a non-rotational state. The method also includes moving a safety switch to an inactive position to activate a first electrical braking system and then a joystick is moved to rotate the drum. The method further includes moving the safety switch to an active position to cause the first braking system to apply sufficient torque to slow down and stop rotation of the drum. After slowing down the drum, the first braking system is used to retain the drum in the non-rotational state. After a predetermined period to time, a second braking system is activated to retain the drum in the non-rotational state, and the first braking system is deactivated. Before reactivating the first braking system, the joystick is returned to a neutral position.
